without sulcus, elytra irregularly punctured, legs siender, the pos- 

 lerior femora double the Ihickness of the others, the anterior 

 and intermediate tibise unarmed, non sulcate, posterior ones 

 mucronate, their metatarsus as long as the following joints toge- 

 ther, claws appendiculate, prosternum invisible between the coxse, 

 the anterior cavilies closed. 



Allied to the Indian genus Micmphthona Jac. but the antennes 

 much more robust, the joints shorter and thicl^ened, the anterior 

 tibiae without spine and the posterior femora less strongly incras- 

 sate; this genus seems another transitionary form between the 

 Galerucinœ and Halticinœ in which the invisible prosternum agrées 

 with the first named group and the distinctly incrassate posterior 

 femora with the other. 



MESOPA FULVIPES sp. n. 



Below black, above seneous or dark cupreous, the basai joints of 

 the antennaeand the legs fulvous, head and thorax minutely granu- 

 late and finely punctured, elytra strongly and closely punctured, 

 depressed below the base. 



Lenght 3 mill. 



Head broad, closely and rather strongly punctured, minutely 

 granulate, cupreous, subopaque, with a short but deep elongate 

 fovea above the antennae, eyes large, frontal élévations absent, 

 carina short but distinct, antennaelong and stout, the lower four or 

 five joints fulvous, the others fuscous, first joint rather long and 

 stout, second one small, third, about a third shorter Ihan the fourth 

 joint, the rest rather thickened, equal ; thorax subquadrate, about 

 one half broader than long, the sides perfectly straight, the angles 

 thickened, the anterior and posterior margin straight, the surface 

 sculptured like the head, the sides more closely punctured than the 

 middle, scutellum black; elytra wider at the base than the thorax, 

 rather strongly depressed below the base, very closely and strongly 

 punctured, the punctuation scarcely finer near the apex, legs 

 fulvous, the tarsi slightly fuscous at the apex. In some spécimen 

 the colour of the upper side is of a more greenish tint. 



CHAL.ENOSOMA VIRIDIS sp. n. 



Below blackish, above metallic green, antennse and legs fulvous, 

 head and thorax impunctate, the latter obsoletely transversely sul- 

 cate, elytra parallel, fmely rugosely punctate.
